Grip Point Linkage

A grip point linkage is a geometric constraint that binds the parts of a pipe or duct line together. A grip point linkage is created automatically in the following cases.

• Upon the addition of a line in the joint of a pipe/duct and a pipe/duct component.
• Upon the addition of a component in the joint of a pipe/duct and a component.

You can also add a grip point linkage between parts – see Add a Grip Point Linkage. You can view the grip point linkages of a part as follows:

1. Select a part or a component.
2. Right-click to open the context-sensitive menu.
3. Select Constraints.
4. Select grip point linkage from the dialog box list. The program will mark the part to be linked in the model.

   

5. If necessary, you can remove a grip point linkage by selecting Delete.
6. If necessary, you can edit a grip point linkage by selecting Edit.

   Rotation is a property of a grip point linkage. You can prevent or allow rotation between pipes and pipe parts that belong to a grip point linkage. Fill in a rotation angle value in the dialog box, if you wish to allow the component to rotate around the X, Y or Z axis. Define the rotation using the right-hand rule. The thumb will point in the direction of the axis, and the fingers in the fist will determine the direction of positive rotation.
